Exploring the limitations of 14C bomb-pulse dating on human tissue samples

The aim of this work, which will be part of the PhD work of the author of this report, was to evaluate the precision and accuracy expected from bomb-pulse dating of human tissue, focusing on the uncertainties introduced by variation in 14C in the human diet. Such variations may be caused by releases from nuclear installations, hospitals and laboratories using 14C, use of fossil fuels as well as va

The perfect fieldwork

InvitedPaper presented at conference/seminar on difficult fieldwork, discusses compromises that ethnographers will have to make as their fieldwork becomes more fragmented and their study objects more suspicious, especially when studying elites; the possibility of any solidarity or empathy with the people we study may be declining.

Understanding the leadership role of the board chairperson through a team production approach

Current corporate governance recommendations – rooted in an investor-based shareholder supremacy model – often narrowly discuss the issue of board leadership as whether or not there is a separation of the CEO and chairperson positions. In this article we employ a team production approach to better understand the leadership role of the board chairperson. We argue that effective board performance is

Crack density tensor inversion for analysis of changes in rock frame architecture

This paper presents a development of the use of multi-axial ultrasonic data for the quantification of extrinsic, crack or grain-contact induced elastic anisotropy in core samples with application to a UKCS oil field. An approach for inversion of multi-axial velocity measurements is presented, which extends the previous work by Sayers (2002) for the determination of second- and fourth-order crack d

Magnetic phases near the Van Hove singularity in s- and d-band Hubbard models

We investigate the magnetic instabilities of the nondegenerate (s-band) and a degenerate (d-band) Hubbard model in two dimensions using many-body effects due to particle-particle diagrams and Hund’s rule local correlations. The density of states and the position of the Van Hove singularity change depending on the value of next-nearest-neighbor hopping t′. The Stoner parameter is strongly reduced i

Software Configuration Management Problems and Solutions to Software Variability Management

These days more and more software is produced as product families. Products that have a lot in common, but all the same vary slightly in one or more aspects. Developing and maintaining these product families is a complex task. Software configuration management (SCM) can, in general, support the development and evolution of one single software product and to some degree also supports the concept of
